Plugging device for ship

Abstract

The invention provides a plugging device for a ship. The plugging device for the ship comprises a box body and a rotating handle screw; the box body is a cavity box body and comprises a side wall, a rotating cover plate and a fixed cover plate which is connected with the bottom of the side wall; a pipe part parallel to the side wall is arranged at the center of the fixed cover plate; the center of the rotating cover plate sleeves the pipe part and can rotate along the pipe part; a pressure relief port is formed in the fixed cover plate; the rotating cover plate can rotate to plug the pressure relief port; and after the rotating handle screw penetrates through the pipe part from one side of the side wall, the rotating handle screw is tightly connected with the fixed cover plate by using a rapid tightening device. According to the plugging device for the ship, due to adoption of a combined form of the fixed cover plate and the rotating cover plate, the rotating cover plate rotates to the position where the pressure relief port of the fixed cover plate is not plugged when the plugging device for the ship is in fixed operation so that the pressure of water flow is relieved from the pressure relief port; and then the rotating cover plate is rotated to a position of plugging the pressure relief port so as to plug the pressure relief port; therefore, the plugging device for the ship is simple, convenient and fast to operate.

Description

technical field [0001] The invention relates to the field of marine leak-stopping devices, in particular to a marine leak-stopping device. Background technique [0002] With the development of the shipping industry and the increase in the density of navigation, the environment in which ships sail, berth and operate is complex and changeable. Accidents are common. Hull damage reduces the stability of the ship, reduces the reserve buoyancy, brings great harm to the ship, and directly threatens the vitality of the ship. [0003] When the hull is damaged and water enters, leak plugging and drainage are the primary tasks. Currently ships are equipped with plugging equipment, and the plugging box is a standing equipment for ship plugging. The existing leak plugging box adopts an integral box structure, and is usually locked and fixed by a screw with a rotary handle. During the leak plugging operation, the impact of the water flow is relatively large, the operation is difficult ...

AI Technical Summary

Problems solved by technology

The existing leak plugging box adopts an integral box structure, and is usually locked and fixed by a screw with a rotary handle. During the leak plugging operation, the impact of the water flow is relatively large, the operation is difficult for personnel, and the box fixing operation (that is, the screw and the nut are locked together) takes a long time , the operation is difficult, and the plugging process cannot be rapid, timely and effective
